title: Glomus tumour in the forearm: a case report and review of MRI findings.
abstract: Glomus tumours are uncommon benign neoplasms characterised by the proliferation of modified smooth muscle cells known as glomus cells. Glomus tumours are well described in the extremities, particularly in the sub-ungual region and MRI is well established as the investigation of choice. However, a significant proportion of glomus tumours are extra-digital, but the discussion of MRI findings of extra-digital tumours is limited and restricted to case reports. We present a case of a solitary painful forearm lesion in an 81-year-old man, and review the English literature on extra-digital glomus tumours documenting MR imaging features. Radiologists should be aware of the existence of these lesions, particularly in the setting of chronic pain and focal tenderness.
